y y FLEXIBLE TUBE A i n A Application filed October 107 `1930. Serial-VNO.. 87.211,

This invent-ion relates to flexible tubes used vide a flexibletube 5 Which isof conventional as containers .for paste or'otherplastic subform in; so far .as the structure of the tube stances of various kinds andclass'es, wherein 'proper is concerned, said tube having a flared Y, Y the substance employed in the'container is discharge end 6,. terminating in a discharge discharged from a nozzle end by the iiexure spout 7, normally closed by a removable cap .55 or compression of the Walls of the container; 8 as in other paint and cream tubescommonly and the object of the invention is to provide a known in the art. The Wall ofthe tube 5 is container of the class specified, the body composed yof thin, flexible and compressible structure of which is cylindricalin'form from material, facilitating the discharge of lthe m the discharge end to the closed bottom Wall contents 9 from the tube.V Y 60 thereof, thus facilitating the placement of In other tubes ,of this class, after the conthe container in a tubular case or holder of a tents 9fhave been passed into the tube through diameter slightly greater than the diameter the open end 10 thereof, the tube is closed by of said tube; a further object being to profolding said open end upon itself, and it is comparatively small in size whereby the same end, in Which'operation, the metal of thetube may be placed in a pocketbook, vanity case is flaredlaterally. y Y or the like or carried in a pocket of a garment In carrying my invention into effect, after v i so that the contents of the tube Will be accesthe contents .p9 Vhave been placed inthe tube, a 1m sible for use at all times; a further object becup-shaped closure wall 11 is forced upon the l' iiig to provide an improved method of concontents 9 and disposed in a countersunk rela structing the sealed and closed end of tubes tion within theopen end 10 of the tube in the of the class under consideration so as to mainmanner shown in Fig. 1 of the drawings. i `j tain the diameter of the tube throughout the The closure 11' is cylindrical informand has entire length thereof; and With these and a comparatively `Wide,.peripheral Wall. 12, 75 other objects in vieiv, the invention consists in which extends outwardly in Aparallelism tol a device of the class and for the purpose thewall of the tube 5, fitting snugly therein. specified, which is constructed in accordance After theY closure Wall 11 has beenl placed in With'the method hereinafter more fully deposition as shown in Figpl, the projecting "U Siflbd and Clamededge lOa'yof the tube isturned inwardly and s The DVGIIOII 1S fully CllSClOSed 111 the Olaround the WjalllQ as Seien at 13111 2 0f, lowing Specification, 0f which the ziccoii'ipaiiy-V the drawings, thus retaining the closure 11 in mg dmwlngs form a Part, 1n WhlCh th?

It i Fig. 4 is a detail view of one of my imisalso preferred that the tube belenclosed iii proved containers, indicating the'method of a suitable Wrapper or sheet 15 which passes i .arranging the same in a case or holder. over the lower end ofthetube andonto the 5 In carrying my invention into effect, I proouter face of the tube to any desiredy degree J` of its length. This outer'vvrapping sheet Y need not necessarily be employed.

It Will be understood tha-t a tube constructed in the manner above set out will be cylindrical in form and of substantially the same diameter throughout its entire lengt-h, thus facilitating the placement of the entire y device, in a case or holder indicated in dotted lines in Fig. 4 of the drawings, and consisting of a tubularl part I6 and a cap I7 detachablel With respect to the part 16. The case or holder is constructed of a strong, non-collapsible material so as to prevent lexure of the tube 5 in carrying the same about in a purse, vanity case or in the pocket.

My improved container lis adapted pri marily for' use Vas a container for paste, creams and other substances that are used from time to time through the day, thus facilitatingthe convenient'carrying of such containers, and the same time, maintaining a relatively small package' as compared with the placement of a. tnbe'of vconventional form into a'case or holder Which Would be large enough to receive the conventional form of flexible tubes.

' It Will be apparent that my improved tube may be constructed in'very small as Well as comparatively large tubes to suit the particular kind and class of product to be marketed therein, as Well as tobe consistent with the use of the tube. While I have shown certain details of construction for carrying my in` vention into eect` it will be understood that I am not necessarily limited to these details and various changes in and modifications of the construction herein shown and described maybe made Within the scope ofthe appended claims Without departing from the spirit of myxinvention orsacriiicing its advantages.v Having fully described my invention,-What I claim as new and desire to secure by Letters Patent, is: y

Y l. An article of manufacture of the class described comprising a flexible containerA tube having a contracted dischargeat'one end and a removable capl controlling said discharge, said tube beyond f the discharge having straight Walls and being 'of the same cylindrical cross section throughout the entire length thereof, a cup-shaped closure member of rigid material arranged Within the'boundary Walls of the other end of the tube and Ysecured thereto, said member opening out- Wardlythrough said end of the tube to form a chamber in said end, the side Walls of the cup-shaped member extendingparallel With and abutting the corresponding Walls of the tube, and said cup-shaped member being secured to the tube by folding the second named end of the tube around the4 peripheral Wall of said cup-shaped member, and a filler placed in the chamber of said cup-shaped member, the outer surface of the filler being flush With the second named end of the tube.

2. An article ofV manufacture of the class member opening outwardly through saidend l of the tube to form a chamber in said end, the side Walls of said cup-shaped member being straight and extending parallel With and abutting the corresponding Walls of the tube, and means arranfed in the chamber of said cup-shaped member and cooperating With the Wall of the tube for forming a flush and'flat outer surface to said end of thetube and for aiding in supporting said member in the end of the tube.

In testimony thatl I claim the foregoing as my invention I have signed my name this 9th day of October 1930, v
